An illness marked by a strong dislike or hatred for something without any known reason behind these feelings

Raseri wasn't sure what exactly made him hate skylights in houses; he just did. It's rumored that Raseri suffers from Aasgier's Syndrome.

Despite being dubbed by many as "tennisace," the man, who was known by many to be afflicted with Aasgier's Syndrome, actually hated tennis for some unbeknownst reason. He would have rather been known as "golface."
